​The ​U.S. Environmental Protection ‌Agency on ​Thursday proposed easing heavy-truck ‌and engine emissions rules adopted under Democratic President Joe Biden in ‌2023.

The EPA said it ‌was proposing scaling back emissions warranty requirements and providing additional ⁠lead ​time ⁠before longer regulatory useful life requirements ⁠take effect.

The EPA, which ​noted that some 2027 medium ⁠and heavy-duty engine development programs ⁠have ​experienced technical challenges, is proposing allowing manufacturers to ⁠continue to sell current products while ⁠they ⁠complete development of 2027-compliant engines.
